“How long should it last?”  That’s a question we ask when we buy pretty much anything.  Below we provide some estimates of how some common household products should last.  A few caveats:

  1. These are estimates and results can vary widely.
  2. To make sure you know when a product’s useful life may end, you need to know when it began. So save receipts and keep a record.  On some items, such as your furnace or AC unit, you can actually tape the purchase date on the unit.
  3. If you don’t take care of the items (annual maintenance, cleaning, etc.), they won’t last as long.
